Why would I need another endodontic procedure?
A tooth may not heal as expected after initial treatment for a number of reasons:

• Narrow or curved canals were not treated during the initial procedure
• There was a delay in placement of the crown or other restoration following the endodontic treatment
• Salivary contamination occurred inside the tooth

Sometimes, a new problem might jeopardize a tooth that was successfully treated:

• New decay exposes the root canal filling material to bacteria, causing infection
• A loose, cracked or broken crown or filling exposes the tooth to infection
• A tooth is fractured

What happens during retreatment?  
If you choose retreatment, we reopen your tooth and remove the post and core material in order to access the root canals.

We clean the canals and search for additional canals or unusual anatomy that requires treatment.

When the canals are clean, we will fill and seal them and place a temporary filling in the tooth. If they are narrow or blocked, endodontic surgery may be necessary.

Your dentist then will place a new crown or other restoration on the tooth.
